The Queen "did not get on" with Princess Diana, one of her closest confidantes has revealed.

Lady Kennard, a close companion of the Queen for decades, tells in a BBC documentary how the late Princess of Wales had been "very damaged by her background and her childhood".

In a rare interview, Prince Andrew's godmother adds: "The Queen would never quite understand what Princess Diana was about - it would be impossible."

But the comments - in an interview for the documentary series Queen and Country - were called "harsh and not fair" by one of Diana's close friends, Vivienne Parry.

Lady Kennard told writer and broadcaster William Shawcross: "I was always surprised that they didn't get on... the Queen would not have a row with anyone - but she was rather surprised by many things [about Diana]."
